Question

我试图为窗口加载执行添加事件处理程序的简单任务。我正在使用Visual Studio 2017.当我输入Loaded=""并使用IntelliSense添加新的事件处理程序时，我收到错误消息＆＃34;确保事件失败＆＃34;而没有其他信息。有什么问题？

XAML：

<Window x:Class="MLD_UI_1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Loaded="">
    <Grid Background="{StaticResource MainBackgroundBrush}">

            <ColumnDefinition Width="*" MinWidth="100"/>
            <ColumnDefinition Width="10"/>
        </Grid.ColumnDefinitions>
        <Border BorderThickness="2 2 1 2" BorderBrush="Black" Grid.Column="1" Grid.Row="1" Background="{StaticResource UvGradientBrush}" CornerRadius="5 0 0 5"/>

        <Border BorderThickness="2 2 1 2" BorderBrush="Black" Grid.Column="1" Grid.Row="3" Background="{StaticResource GradientBrush}" CornerRadius="5 0 0 5"/>
        <Border BorderThickness="1 2 2 2" BorderBrush="Black" Grid.Column="2" Grid.Row="3" Background="{StaticResource GradientBrush}" CornerRadius="0 5 5 0"/>

            <TextBlock Text="UV" FontFamily="Tahoma" Foreground="White" VerticalAlignment="Center" FontSize="20"/>
        </StackPanel>
        <StackPanel Grid.Column="2" Grid.Row="1" Orientation="Horizontal" Margin="10 0 10 0">
            <TextBlock Text="IR" FontFamily="Tahoma" Foreground="White" VerticalAlignment="Center" FontSize="20"/>
        </StackPanel>
        <Image x:Name="imagePane1" Grid.Column="1" HorizontalAlignment="Stretch" Grid.Row="2" VerticalAlignment="Stretch" Margin="2 2 2 2"/>
        <Image x:Name="imagePane2" Grid.Column="2" HorizontalAlignment="Stretch" Grid.Row="2" VerticalAlignment="Stretch" Margin="2 2 2 2"/>
    </Grid>
</Window>
